Recombinant Human NRG4

Background

Neuregulin 4 (NRG4) is a member of the neuregulin family, which consists of growth factors that play critical roles in cell signaling, development, and homeostasis. NRG4 primarily acts through the ErbB family of receptor tyrosine kinases, notably interacting with ErbB4 to initiate downstream signaling pathways. This signaling is involved in a variety of physiological processes, including metabolism, tissue repair, and the regulation of energy balance. Research suggests that NRG4 may have protective roles in metabolic disorders, such as obesity and type 2 diabetes, by modulating insulin sensitivity and inflammatory responses in key tissues like the liver and adipose tissue. Additionally, NRG4's role in neuronal and cardiac development has also been noted, highlighting its importance across diverse biological systems. Further exploration of NRG4's signaling mechanisms may provide valuable insights into therapeutic strategies for metabolic and neurodegenerative diseases.
